Polk's ultra-compact Blackstone TL1 proves that you don't need a big speaker to enjoy big sound. Thanks to Polk's decades of speaker-building expertise, along with some pretty advanced driver technology, you'll experience effortlessly clear sound. And if you own a flat-panel TV, the TL1's high-gloss finish will complement it perfectly.

Advanced technology produces astonishingly realistic sound
The "TL" refers to Polk's "Time Lens" technology, which aligns the drivers in such a way that all the sounds reach your ears at the same time. This improves the speaker's imaging and soundstaging, so that you'll start to forget you're watching a movie and really feel like you're part of it. An "acoustic lens" in the speaker grille disperses sound waves in a way that makes your movie and music soundtracks sound larger and more open.

The "aperiodic-tuned rear port" controls air flow in and out of the enclosure, much like a breathable membrane. It gives the TL1 the acoustic benefits of both a sealed and a ported enclosure, including better bass extension and a pleasing mid-bass boost. It also means you can place this speaker in the open or against a wall, and still get great sound.

Easy speaker placement
The TL1 has a keyhole slot in the back for easy mounting to your wall straight from the box. You can also use the threaded insert to attach it to an optional speaker bracket or stand. Create your own home theater system using a combination of black TL1s in the front of your room and white TL1 surrounds in the back. Or add a pair in either color to the TL1600 system to get even more engaging, seven-channel surround sound.

Why choose bookshelf speakers?

Bookshelf speakers may be small in size, but they can deliver surprisingly big sound. Some ultra-compact models even fit on a desktop. Most are right at home in tight spaces like shelves, so they're usually good choices for your home theater's rear channels. For the best performance, try placing bookshelf speakers on solid speaker stands to help the sound really "open up." If you want full bass impact, add a powered subwoofer and enjoy punchy sound that's as deeply satisfying as that of floor-standing speakers.

Great Speaker

Great sounding, small, easily mountable speaker for ceiling mounted surround sound. I didn't not want to have to patch and repair the gang box hole that was prewired by the builder. Every one was located next to a stud for all 6 speakers, so I utilized pin point gang box mounts with this speaker. Looks great and was very easy to install.

Pros:Small, great sound. Went with white to blend into the ceiling. Lightweight, easy to mount.

My Second Pair

Just ordered two more of these speakers today. They may be small but they have big sound. I like the fact they don't take up too much space. Only gave this speaker four starts because I'm having trouble attaching them to my speaker stands. Having to go to the hardware store to get some different hardware but once I do that they will do the job. Also, the tech I talked to today was very helpful and knowledgeable.

Perfect!

Just what I was looking for to replace and old set of large speakers. The sound quality is VERY good and the size is perfect. I keep asking myself WHY I waited so long to replace the old ones. I didn't give them 5 stars as I am just not that knowledgable about speakers.

Fits the bill

I was looking for rear speakers for my home theatre setup and these speakers filled the bill. Coupled with the Crutchfield recommended Sanus Systems HTB7 speaker stands, these speakers fit the bill. Didn't give them five stars because I don't rate anything that high.

Sweet sound

Great sound. Nice to have two satellite speaker mounting options. One warning though. I took off a star because the recessed mounting screws on the satellite speaker. IF you use DEFTECH PROMOUNT 80 speaker mounts, you are going to have to widen the hole that leads to the screw mount because of the way the promounts work. You will also have to add (lock) washers when using the promounts since the screw holes are recessed into the back of the satellite. I bought two to add to the Polk Audio Blackstone TL1600 to make it 7.1

Good bookshelf speakers

I have been very happy with these as the left and right front channels of a 5.1 surround system. The fit nicely in our built in shelving and are attractive. Their sound is clear with good dynamic range. I recommend them.

AMAZED!

I was so amazed with these speakers! I ordered one pair to replace the old blown Philips surround sound speakers I had. WOW! The clarity and volume these little guy produce for the price is unbelievable. Now I will have to buy another pair to replace the other two old speakers as these over power the old ones lol.

Fantastic Speakers!

I purchased 2 of these speakers after receiving advice from Crutchfield rep (Dylan)....he was absolutely right, I an older stereo system that had HUGE speakers which finally broke. These bookshelf speakers are the best sounding and perfect fit for my stereo system. I would absolutely trust a Crutchfield Rep to recommend another system or unit to me in the future. The sound, quality everything made this purchase worth the price! I so recommend anyone thinking about purchasing these speakers to do so or if my recommendation isn't enough, speak with one of the Crutchfield people -they know their stuff.

Pros:Excellent sound quality, can be placed anywhere and are small enough that they won't be noticed.

A remarkable small speaker

My experience with audio products goes back to the early '60s, when speakers were judged by size and weight - the bigger and heavier, the better. Time and technology have rendered that method of assessing performance irrelevant, as is demonstrated by this small speaker. When one takes one out of its box, one's feeling is that fine performance from such a small unit will be impossible, but that is wrong - it worms very well. I had been trying to improve the performance of the side surround channel in my system, and had tried several different speakers that I had on hand, without getting the effect that I wanted. I decided to try the TL1s, since they had received good reviews, and were modestly priced. I am very glad that I did, since I achieved exactly what I had not been able to do previously: the high frequency response and presence of my side channels has been considerably improved.

Polk Audio Blackstone TL1

I recently purchased a Polk 5.1 surround system, but wanted to upgrade to 7.1. These speakers matched the system I bought perfectly. They look great, very compact with great sound. I am very impressed with Polk sound.

Polk Audio BlackstoneT TL1

Great value. I'm using these as surround speakers; however when they arrived I auditioned them as main speakers (with Dyna Audio Sub). Fantastic sound right out of the box. They opened up even more after a couple days of break in. the sound stage is open and wide, liquid midrange and non-fatiguing trebble. Clear open sound. Unfortunately, there is ZERO useful bass. Even though there was a sub, there was a noticeable gap in the midbass. I didn't play around with the low pass x-over on the sub; that probably would have helped. Forget about using these alone though. They remind me of NHT Super Zero's from the 90's...only better!

Exactly what I needed

I already had a 5.1 Polk Blackstone 1600 speaker setup but wanted to add two more speakers for "height" in my 7.1 configuration. I could not find these speakers at any local store and one place wanted $20 more each than Crutchfield. The speakers are great, I already knew that. The ease of ordering from Crutchfield was amazing. They arrived exactly when promised, well protected in their original boxes and placed into a larger box with plenty of packing peanuts to prevent any shipping damage. I'm sold on Crutchfield.

Pros:Small speaker / BIG sound. Great product. Have not been disappointed

Amazed

I'm amazed at how much rich sound comes out of these little speakers. It's like i've been missing out on everything I was listening to prior to this purchase. i'm on a budget, but was in serious need of a new system for my small house in the city. I paired these up with an Onkyo TX-8255 receiver, and a Polk PSW-108 powered sub. I've barely watched television since the purchase. If you're on a budget, or don't have a ton of space but want great quality sound, these would be a smart purchase.

TL1

Used as surround speakers on a 5.1 system @ 100w/ch crossed over at 120hz. These TL1s are smooth on the highs. When I read reviews I look for someone to mention whether a speaker is harsh on the highs or not and these are very comfortable on the ears. For what it's worth, i think these are better voice matched to my monitor 70s than were the monitor 30s they replaced. I'm extremely pleased with these as surrounds- 5 stars for the class they're in. Beautiful white finish and are clean looking on a white wall. Bottom line: they sound great for being 2.5" drivers.

Big Sound

Purchased these to a Polk TL1600 to complete a 7.1 system. Very impressive construction/finish, and the sound is spectacular. Its amazing how much full spectrum sound can come from such a compact speaker. Also look great mounted on the wall!

Polk never let me down!

Bought these when i ordered my TV for two reasons 1. Ive been looking for new
surround speakers since the ones i have now are huge (polk R150) 2. Because if
bought together with my TV i save $$. Wow these things are really crisp, great
sound at all volumes. Not much mid bass but its cool because im using them as
surround speakers. Highly recommended o_O

Product Research

Driver Technology

Dynamic Balance Driver Technology: Polk Audio's patented Dynamic
Balance process allows Polk to design their drivers specifically for flatter
frequency response, revealing the sharpest details and a more lifelike
transparency, with absolutely no strain even at high volume. It's a bold, rich,
warm, and lifelike sound.

Time Lens Technology: The sophisticated laser alignment of the
"acoustic center" of the Blackstone TL tweeters with their accompanying drivers
results in far superior imaging. The acoustic centers of the tweeter and
mid-range woofer are aligned, creating a crisp accurate soundstage. The acoustic
centers of the tweeter and mid-bass driver are located in the same plane for
superior imaging, while the acoustic lens incorporated in the grille smoothes
the tweeter's frequency response.

Frequency Response: The overall frequency response is
120Hz to 22kHz and the -3dB frequency response is 135Hz to 20kHz.

Additional Speakers: The TL1 satellite speaker will require
a powered subwoofer (107PSW111,
sold separately) for full-range sound. You can also add addition TL1 series
speakers for 2.1, 3.1, 5.1, 6.1 and 7.1 channel home theater configurations.

Enclosure Design

Curved Enclosure Design: The Polk Audio Black Stone TL1 satellite
speaker employs non-parallel surfaces that not only lead to a stronger, more
rigid and acoustically inert enclosure, but they also result in less audible
coloration from internal surface resonances.

Integrated Acoustic Lens: An innovative acoustic lens incorporated
into the grille produces a high frequency response so smooth that it delivers a
balanced, realistic performance. An acoustic lens is molded into the back of the
speaker grille and helps create imaging frequency balance previously impossible
in small high-performance satellite speakers.

Aperiodic-Tuned Rear Port: An aperiodic-tuned rear port enables better
blending with a subwoofer. This design combines the bass extension of an
acoustic suspension enclosure with the mid-bass boost of a ported enclosure by
controlling airflow through the port for better extension without distortion.

High-Gloss Finish: The Polk Audio TL1 satellite speaker features a
durable, deep automotive-strength high-gloss finish that matches today's most
stylish flat-panel TVs. The TL1 is available in a high-gloss black or white
finish.

Connections

5-Way Binding Posts: The Polk Audio Black Stone TL1 is equipped with
one pair of 5-way binding posts to ensure a secure connection to many types of
speaker cables and connectors. The binding post terminals will accept banana
plugs (single or dual), pin-connectors, spade-connectors, and bare wire (18-12
AGW).

Mounting Options

Rubber Feet: The Polk Audio TL1 features three integrated rubber feet
so you can sit the speaker on a stand or shelf securely.

Wall Mountable: The TL1 satellite speaker feature a single keyhole
slot on the back of the cabinet for wall-mounting the speaker without any
additional wall-mount bracket (mounting screws not supplied). There is also a
1/4"-20 threaded insert on the back of the loudspeaker for mounting the speaker
to the wall using an optional articulating bracket (sold separately).
